Why you sold so many Stylus Pens one time, I don't want to buy so many?

We can't retail it one by one, because the pens are in pack, and also you know that nowadays the stylus pen are really more and more useful in life, after that it's too small that peple lose it before it's broken, so it's acceptable.

How the stylus works?

The tablets are touch-sensitive surfaces that detect the pressure applied by a stylus pen. This works via changes in magnetic fields or by bringing together two resistive sheets, for magnetic tablets and resistive tablets respectively. Tablets allow users to interact with computers by touching through a stylus pen, yet they do not respond directly to a user's touch.
